<h2>Description</h2>
Opens mp1/2/3 audio files directly and normalizes output to 100% if requested.<br>
<br>
Take care when testing: by opening the AVS-script the whole file gets scanned
in order to return the exact sample number when <i> normalize=false</i> (default) this is done with partial
decoding (~20sec for
one hour audio on my PC). When <i> normalize=true</i> it is much slower (~100sec).<br>
<br>
Version 0.2 creates a small file .D2A after the first scan, so there is no multiple
scanning necessary.<br>
<br>
When backward jumps are requested, the seeking is always done in fast mode from
frame 0 to the requested frame.<br>
<br>
Along with the audio, a small 8x8 video is generated, so you always have to put
MPASource as SECOND argument in AudioDub.<br>
<br>
<strong>Example</strong> :<br>
LoadPlugin(&quot;C:\myprojects\mpasource25\release\mpasource.dll&quot;)<br>
<br>
V=BlankClip(height=100, width=100, length=20000, fps=25)<br>
A=MPASource( &quot;d:\_mp3\pop\liquido - narcotic.mp3&quot;, normalize = false)<br>
AudioDub(V,A)
